Matt,
I also havre tried these type of work arounds. The problem is you have one version in a folder that has been edited and different from the version in another folder.

Actually, the option>preferences>notation>transpose almost does the trick. Notice that if you involg a transpose, the chord you enter on the keyboard is not what will be displayed on the screen. Let's say I started a new somng in concert C and transposed to a tenor sax. The display would change to a D, correct. But now I cannot edit the song in the transposed world and if I want to enter a E, it shows up as a F#. Seems like it would be easy to apply the transpose to the keyboard as well. And then to make things easier, put a button on the front window to indicate and allow change to the transposition.

With this fix, the song would stay in the concert key and mixups could be avoided, yes? Let's tell Peter.

BiaB is a totally great program. However, I think it trys to be to much sometimes. I bet if a poll were taken as to what features were actually used, many like the "sound blaster control panel", and "auto name a song" would not be used very often.

Thanks for the spelling correction. I think my keyboard must have been in transpose mode.
